It is commonly thought that the distinction between subjectively valid judgements of perception and objectively valid judgements of experience in the Prolegomena is not consistent with the account of judgement Kant offers in the B Deduction, according to which a judgement is ‘nothing other than the way to bring given cognitions to the objective unity of apperception’. Contrary to this view, I argue that the Prolegomena distinction maps closely onto that drawn between the mathematical and dynamical principles in the System (...) of Principles: Kant’s account of the Prolegomena distinction strongly suggests that it is the Analogies of Experience that make it possible for judgements of perception to give rise to judgements of experience. This means that judgements of perception are objectively valid with regard to the quantity and quality of objects, and subjectively valid with regard to the relation they posit between objects. If that is the case, then the notion of a judgement of perception is consistent with the B Deduction account of judgement. (shrink)

The article presents the views of Benedict Bornstein, formulated in his early writings, such as The Pre-established Transcendental Harmony as the Foundation of Kant’s Theory and The Basic Problem of Kant’s Theory of Cognition. These views pertain to the Kantian dualism of concepts and intuitions and they are presented against the background of the contemporary debate about the contents of perceptual experience. Recognizing the rightness of Bornstein’s claim about the non-conceptual character of the Kantian intuitions, I criticize Bornstein’s solution to (...) the problem of dualism, which necessitates an appeal to the conception of transcendental harmony, established by an act of God’s will.

This work examines Kant’s remarkable decision to rewrite the core argument of the first Critique, the Transcendental Deduction of the Categories. I identify a two-part structure common to both versions: first establishing an essential role for the categories in unifying sensible intuitions; and then addressing a worry about how the connection between our faculties asserted in the first part is possible. I employ this structure to show how Kant rewrote the argument, focusing on Kant’s response to the concerns raised in (...) an early review by Johann Schultz. Schultz’s dissatisfaction with the original Deduction lies in its second part, and Kant’s subsequent revisions are focused on providing a better answer to this how-possible question. The new Deduction offers a more direct and convincing account of how our faculties work together to make experience possible. (shrink)

Hermann von Helmholtz’s work on perceptual science had a fundamental impact on Neo-Kantian movements in the late nineteenth century, and his influence continues to be felt in psychology and analytic philosophy of perception. As is widely acknowledged, Helmholtz denied that we can perceive mind-independent properties of external objects, a view I label Ignorance. Given his commitment to Ignorance, Helmholtz might seem to be committed to a subjectivism according to which we only perceive properties of our own representations. Against this, I (...) argue that for Helmholtz, the properties we perceive are not monadic properties of either the subject or the object. Rather, Helmholtz endorsed a relationalism about the properties we perceive: the properties of objects we perceive are all relational properties. I then suggest that once we take into account oft-neglected terminological distinctions in Helmholtz’s corpus, we are better able to make sense of his commitment to relationalism. (shrink)

I give an argument against nonconceptualist readings of Kants claim that intuitions and concepts constitute two distinct kinds of representation than is assumed by proponents of nonconceptualist readings. I present such an interpretation and outline the alternative reading of the Deduction that results.

This article advances a new account of Kant’s views on conceptualism. On the one hand, I argue that Kant was a nonconceptualist. On the other hand, my approach accommodates many motivations underlying the conceptualist reading of his work: for example, it is fully compatible with the success of the Transcendental Deduction. I motivate my view by providing a new analysis of both Kant’s theory of perception and of the role of categorical synthesis: I look in particular at the categories of (...) quantity. Locating my interpretation in relation to recent research by Allais, Ginsborg, Tolley and others, I argue that it offers an attractive compromise on this important theoretical and exegetical issue.

Does Kant hold that we can have intuitions independently of concepts? A striking passage from §13 of the Critique of Pure Reason appears to say so explicitly. However, it also conjures up a scenario where the categories are inapplicable to objects of intuition, a scenario presumably shown impossible by the following Transcendental Deduction. The seemingly non-conceptualist claim concerning intuition have therefore been read, by conceptualist interpreters of Kant, as similarly counterpossible. I argue that the passage in question best supports an (...) underappreciated middle position where intuition requires a pre-conceptual use of the understanding. Such pre-conceptual use of the understanding faces both textual and systematic objections. I show that these objections can be rebutted. (shrink)

One of the central debates in contemporary Kant scholarship concerns whether Kant endorses a “conceptualist” account of the nature of sensory experience. Understanding the debate is crucial for getting a full grasp of Kant's theory of mind, cognition, perception, and epistemology. This paper situates the debate in the context of Kant's broader theory of cognition and surveys some of the major arguments for conceptualist and non-conceptualist interpretations of his critical philosophy.

The problem of Kant’s Neglected Alternative is that while his Aesthetic provides an argument that space and time are empirically real – in applying to all appearances – its argument seems to fall short of the conclusion that space and time are transcendentally ideal, in not applying to any things in themselves. By considering an overlooked passage in which Kant explains why his Transcendental Deduction is ‘unavoidably necessary’, I argue that it is not solely in his Aesthetic but more so (...) in his Deduction where he intends to provide his argument for the transcendental ideality of space and time. His Deduction shows that space and time do not have a valid application to any things in themselves by arguing that the categories do have a valid application to everything in space and time, but that the categories do not have a valid application to any things in themselves.

In an intriguing but neglected passage in the Transcendental Deduction, Kant appears to link the synthetic activity of the understanding in experience with the phenomenon of attention (B156-7n). In this paper, we take up this hint, and draw upon Kant's remarks about attention in the Anthropology to shed light on the vexed question of what, exactly, the understanding's role in experience is for Kant. We argue that reading Kant's claims about synthesis in this light allows us to combine two aspects (...) of Kant's views that many commentators have thought are in tension with one another: on the one hand, Kant's apparent commitment to naïve realism about perception and, on the other, his apparent commitment to the necessity of synthetic activity by the understanding for any kind of cognitive contact with external objects.

Kant calls his Transcendental Deduction "the most difficult thing that could ever be undertaken on behalf of metaphysics" (4:260). Readers have found it not just difficult but downright impossible. I will address two long-standing problems. First, Kant seems to contradict his conclusion at the outset of his proof. He does so in both the 1781 and 1787 editions of his Critique of Pure Reason. Second, Kant seems to argue for his single conclusion twice over in his Critique's 1787 edition. I (...) will propose novel solutions by considering why Kant's Deduction is more difficult than his Transcendental Aesthetic, on one hand, and his 1770 Inaugural Dissertation, on the other. My broader aim is to oppose a subjectivist interpretation of Kant's Deduction with an original interpretation. On the subjectivist interpretation, Kant holds that the categories apply to appearances because appearances necessarily conform to our subjective forms of the understanding. I will argue to the contrary in addressing the first problem. On my interpretation, the reason that the categories apply to appearances is not just because of what our subjective forms of the understanding are. It is because of what objects are as appearances. What are objects as appearances, for Kant? In addressing the second problem, I will argue that they are objects of our possible intuitions and judgments. (shrink)

Against a view currently popular in the literature, it is argued that Kant was not a niıve realist about perceptual experience. Naive realism entails that perceptual experience is object-dependent in a very strong sense. In the first half of the paper, I explain what this claim amounts to and I undermine the evidence that has been marshalled in support of attributing it to Kant. In the second half of the paper, I explore in some detail Kant’s account of hallucination and (...) argue that no such account is available to someone who thinks that veridical perceptual experience is object-dependent in the naive realist sense. Kant’s theory provides for a remarkably sophisticated, bottom-up explanation of the phenomenal character of hallucinatory episodes and is crucial for gaining a proper understanding of his model of the mind and its place in nature.

Call the idea that states of perceptual awareness have intentional content, and in virtue of that aim at or represent ways the world might be, the ‘Content View.’ I argue that though Kant is widely interpreted as endorsing the Content View there are significant problems for any such interpretation. I further argue that given the problems associated with attributing the Content View to Kant, interpreters should instead consider him as endorsing a form of acquaintance theory. Though perceptual acquaintance is controversial (...) in itself and in attribution to Kant, it promises to make sense of central claims within his critical philosophy. (shrink)

The issue of the nature of cognitive experience has been a subject of lively debate in recent works on epistemology, and the philosophy of mind. During this debate, the relevance of Kant to contemporary theories of cognition has been re-discovered. However, participants in this debate disagree whether Kant was a conceptualist or a non-conceptualist, with regard to the character of intuitions. The central point of controversy concerns whether or not Kant’s sensible intuitions involve understanding and have a conceptual content. In (...) this paper, I show that, despite their disagreements, both sides share a number of common presuppositions, which have determined a biased framework for the reading of Kant. My principal aim in this article is to reconcile the case for conceptualism with those interpretations which argue that intentionality and conceptuality can be separated. To achieve it, I present my own reconstruction of Kant’s theory of cognition, relying essentially on Kantian considerations found in the B-version of the Transcendental Deduction, and offer a new interpretation of Kantian conceptualism.

The aim of this paper is to show that attention to Kant's philosophy of mathematics sheds light on the doctrine that there are two stems of the cognitive capacity, which are distinct, but equally necessary for cognition. Specifically, I argue for the following four claims: The distinctive structure of outer sensible intuitions must be understood in terms of the concept of magnitude. The act of sensibly representing a magnitude involves a special act of spontaneity Kant ascribes to a capacity he (...) calls the productive imagination. Contrary to what is assumed by many commentators, it is not the case that the Two Stems Doctrine implies that a representation is either sensible or spontaneity-dependent, but not both. Outer sensible intuitions are both sensible and spontaneity-dependent – they are sensible because they exhibit the kind of structure Kant takes to be distinctive of outer sensible intuitions, and they depend on spontaneity because they are cases of sensibly representing a magnitude.

In the “Second Analogy,” Kant argues that, unless mental contents involve the concept of causation, they cannot represent an objective temporal sequence. According to Kant, deploying the concept of causation renders a certain temporal ordering of representations necessary, thus enabling objective representational purport. One exegetical question that remains controversial is this: how, and in what sense, does deploying the concept of cause render a certain ordering of representations necessary? I argue that this necessitation is a matter of epistemic normativity: with (...) certain causal presuppositions in place, the individual is obliged to make a judgment with certain temporal contents, on pain of irrationality. To make this normatively obligatory judgment, the subject must place her perceptual representations in a certain order. This interpretation fits Kant's text, his argumentative aims, and his broader views about causal inference, better than rival interpretations can. This result has important consequences for the ongoing debate over the role of normativity in Kant's philosophy of mind. (shrink)

What is it that makes a mental state conscious? Recent commentators have proposed that for Kant, consciousness results from differentiation: A mental state is conscious insofar as it is distinguished, by means of our conceptual capacities, from other states and/or things. I argue instead that Kant’s conception of state consciousness is sensory: A mental state is conscious insofar as it is accompanied by an inner sensation. Interpreting state consciousness as inner sensation reveals an underappreciated influence of Crusius on Kant’s view, (...) solves some long-standing puzzles concerning Kant’s difficult doctrine of self-affection, and sheds light on his theory of inner experience.
